Backend Architecture & API Engineering
We build the server-side foundations that enable applications to process information, enforce business rules, and communicate reliably with other systems.
Services
Third-Party System Integrations
We help businesses connect applications, services, and data workflows to reduce manual effort and improve information flow.
What’s included
What this service covers
The main capabilities within third-party system integrations. The scope of each project is agreed with you during discovery.
Specific integrations are assessed according to API access, vendor requirements, available documentation, and project scope.
-
Third-party API integrations
Connecting your software to external services through their published APIs.
-
Payment gateway integrations
Taking and tracking payments through payment gateways, with the result reflected in your own system.
-
Marketplace report processing and reconciliation
Processing the reports that marketplaces provide and reconciling them against your own records.
-
Data import, transformation and validation
Bringing data in from files and systems, converting it to the structure you need, and checking it before it is used.
-
Workflow automation
Removing copy-and-paste between systems by letting data move on its own.
-
Frontend, backend and external service integration
Making sure the parts of your application and the services around it work together reliably.
How we approach it
Practical engineering, shaped around you
We aim to understand the business problem first, then choose a solution that suits it and can be maintained.
- Staff re-enter the same data in more than one system
- Payments or marketplace reports are reconciled by hand
- A vendor offers an API but no ready-made connector
- Data arrives in files that need cleaning before it can be used
- 01
Assess before committing
We check API access, vendor requirements, documentation and scope first, so you know what is feasible before work starts.
- 02
Validate the data
Data entering your system is checked, and mismatches are surfaced instead of being silently accepted.
- 03
Expect third parties to change
External services change over time, so integrations are structured to be maintained and updated.

- 02
Solution Architecture & Planning
We define the proposed scope, key components, integration requirements, milestones, dependencies, and acceptance criteria.
- 03
Design & Engineering
We develop the application, backend services, integrations, and business logic according to the agreed requirements.
- 04
Validation & Quality Assurance
We test implemented functionality, review integrations, resolve identified issues, and validate requirements against agreed acceptance criteria.
- 05
Deployment & Handover
We coordinate deployment and provide the agreed deliverables and handover information.
- 06
Maintenance & Evolution
Where included in the engagement, we support ongoing maintenance, issue resolution, and future improvements.
Questions
Common questions
Which third-party systems can you integrate with?
Specific integrations are assessed according to API access, vendor requirements, available documentation and project scope. After reviewing the system involved, we can tell you what is feasible.
Do you handle payment gateway integrations?
Yes. Payment gateway integration is part of our integration work, subject to the gateway’s requirements and your project scope.
Can reconciliation be automated?
Marketplace report processing and reconciliation is one of the areas we work in. The approach depends on the reports available and the rules your business uses.
